CVEs: CVE-2013-0268

Systems running Red Hat Enterprise Linux 6 can now use Ksplice to

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on RHEL 6 install these
updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y

could use this flaw to execute arbitrary code in kernel mode.
